Referring to theidrawings, the fram e of my-machinc comprises a baseplate 1, and

side frames 2 and 2 which are secured to to their upper edges.

the base plate and project vertically up from it at a sufficientdistance apart to receive andsupport between and on them the variousmechanisms that comprise the several features of it. These side frames 2and 2 are braced by a cross shaft 3, which extends between and throughthem adjacent The top edges of these side standards .are inclineddownward from their rear ends 2 for a portion of their lengths, from theend of which they curve upwardly in a short curve 2 and then extendhorizontally forward 'for a shortdistance, and this end 2 is the frontend of the machine. Upon the side frames 2 and 2 ,'I place anotherframe, which I term the upper or card'bending frame,

which consists of two sides 4 and 4 and these sides fit the inclined andcurved portion of the top edges of the side frames 2 and 2, and aresecured thereto. Above this upper or card bending mechanism, there is acard supporting hopper and feeding mechanism, which'is supported by twobrackets 5 and 5 which bolt to a cross tie frame 5 that extends acrossand between the side .plates 4 and 4 andis bolted to them. Thesedirectly below and in alinement with its vertically reciprocatingplunger 7*, at each complete cycle movement of the machine. Theseseveral cycle movements will be fully described hereinafter.

The base plate 1 is a substantial cast iron platc, and is provided witha pair of lugs 5) and" 9, that project from its left hand side. The lug9 supports a doubl' bearing, which consists of a pair of boxes 10 and10", that are spaced a short distance apart but are placed in alinementwith each other,

and another pair of boxes 10 and 10 also in alinement but spaced apartand arranged to one side of the boxes 10'and 10 The boxes 10 and 10support rotatably a shaft 11, which is the power driven and the drivingshaft of all of the mechanism of my box and label feeding machine. Abelt receiving friction clutch pulley 12, and a reciprocal movementfriction clutch 13, is operatively mounted on the shaft 11 intermediateof its ends. This friction clutch is movedto grip or release the clutchpulley through the medium of a spanner crescent 13, that partiallysurrounds a neck portion 13, that is formed in the hub of the frictionclutch.

This crescent is mounted on and secured to a shaft 11, that is supportedin the bearings 10 and 10 This shaft 11 is slidably mounted in the bear-'ings 10 and 10", and it is adapted to be connected to a handle, which Ido not illus-' trate. as it is a commonly used element, which may bepositioned at the most-convenient point to this machine and to the boxcovering machine that is to be connected to this machine, and is tobefdriven from this box andlabel feeding machine. A collar 13 is securedto the shaft near the box 10, and an expansive spring 13 is placed between it and the hub of the friction clutch, and acts to normally holdthe clutch in engagement with the clutch pulley.

A worm pinion 14- is mounted on and secured to the shaft 11 between theboxes 10 and 10 and meshes with a Worm gear 1%, that is mounted andsecured on the end of a shaft 15, whichl will term-the cam shaft, whichextends across the base from one side frame 2 to the other side frame 2,and is journaled in bearings 15 that are secured to lugs 15 formed onthe lower edge of an (o Z ne shaft 11', in a. beei'in .bending machineto be connected jeet up into than from ilie tziliile.

the feed table, as this right and left hand threaded feed screw allowsthe side guides to be moved simultaneously and in unison toward thecenter of the table to fit smaller sized cards, from the position theyare shown in, in which position they receive between them the largestcards the machine can feed and bend into loose end boxes. The forwardedge of this table is provided at its central portion with a'forwardlyprojecting lug portion 43:, that forms a resting .lace for the centersof large -car ds which iave;aj-tendency to bend outwardly at thedischarge end ,of the feed table. The for ward ends of the verticalflanges 34 of the side guides are provided at their upper and loweredges with projecting lugs 44 and a spindle 45 that is rotatably mountedin the center of the lugs of each of the flanges of each side guide. Acollar 46 is secured to the upper ends of these spindles, and rests onthe upper lug, and the lower end of each spindle projects beyond thelower lug and a bevel gear 47 is secured to it. These bevel gears mesh.with similar sized bevel gears 48, that are shdably mounted on a squareshaft 49, the ends of which are reduced to round shouldered ends, thatare journaled in bearings 50. formed in the upper side frames {and 4 toreceive them, and partially rotate therein. The bevel gears 48 aresecured in adjusted positions on the square shaft when the side guidesare moved 7 toward the center 'ofthe feed table to lit different sizedcards, by a pair of crescent ended plates 51 which are secured to thelower lugs 44 of the vertical flanges'of the side guides. The crescentshaped end of each plate is arranged to project into a neck 40 portion53, which is formed in a hub portion formed on each of these gears.Consequently as the guide plates are moved to ward or away from thecenter of the feed table by their feed screw 39, the gears 48 are movedalong the square shaft and are always held in mesh with the gears 47 byv the crescent plates. On each of the spindles 4-5 of the flanges of theside guides, I mount and secure, preferably by set screws 50 54, aplurality of clips 55, which I term card engaging clips. I preferablyillustrate four of these card engaging clips on each spindle. These cardengaging clips project through openings 56 forl'ned in the flanges toreceive them, to swing inwardly beyond the inner surface ofthe flanges,and they are arranged and adapted to stand with their outer endspointing forwardly toward the discharge end of the feed table and nor-60 mally even with the inside surface of the flanges, and behindaretaining strip 55", which -is secured to the endof each of the sideflanges. These clips are moved by the gears 47 and 48 by means whichwill be presently described, against the opposite sides of the stack ofcards, they being arranged to engage the card next to the end card andmove the whole stack of cards slightly backward in the hopper, and thustake the weight of the whole stack of cards oil of the end card, andthis end card is removed from the stack of cards and from the hopper bya pneumatically operating air suction impulse action and cooperatingmechanism, which I will presently describe. The gear 47 is caused toturn through apa'rtial rotary movement by the gear l8, through themedium of a lever 57, that is secured to and projects from one end ofthe shaft 49, to the outer end of which one end 30 side of the cam disk(34, which is secured on the cam shaft 15. This cam groove is ar rangedto move the rock arm and rod and bevel gears to cause the clips 55, toswing from their normally forwardly projtwting position along the sidesof the flanges of the side guide in which they are out of engage mentwith the cards, inwardly from the opposite sides of the hopper andagainst the cards and backwardly against the cards 1,00 enough to movethe entire stack of cards except the end card backwardly in the hopper,and they move easily backward up the slight incline of the hopper on theendless belt, which in turn moves on the rollers. The air impulse deviceand mechanism that grips the end card and conveys it to the card bender,is constructed and operates as follows: The air ii'npulse'devicecomprises an air suction nozzle 65, which preferably consists of arectangular shaped bar of metal, which is provided with an interior airchamber or aperture 66, and the edge of this nozzle that faces the cardsis provided with a vertical row of air intake or air suction apertures67, which extend into its air chamber 66. This row of air inlet andoutlet apertures faces the discharging end of the hopper, and the nozzleis made long enough 'to engage the full width of the largest cards themachine is. capable of using. I preferably form the air chamber in thenozzle by drilling a hole lengthwise of the nozzle to close to its lower'end, and in order that some of the upper'125 card actuating air holesmay be closed up; at the top of the nozzle, which is necessaryf whencards of different smaller sizes than the largest the machine willreceive are used, as the machine willtake cards varying 1a in size from20% by 13.; inches square down Y to cards 1% by 3 inches square. Iextend sired, and close them, and in order to hold and set the pin atany adjusted point in the length of the nozzle, I place a set screw 69,through its side against the pin. The nozzle is provided .withan airinlet aperture 70, to which a nipple 71 is threaded, and suitable pipefittings are connected to the nipple and extend to and are connected toan air pump cylinder 72, which is mounted on the base plate of theframe. This air pimprylinderis provided with a suitably packed pistonhead -73, and with an operatively connectedfconnecting rod 7 1, theouter end of which is'pivotally connected to one end of a rock arni'75,the opposite end of which is pivotally mounted on a shaft the oppositeends of which are secured in the side frani'es 2 and 2'.

(line end of .a forked lever 76 is pivotally secured to the rock arm 75,intermediate of its ends, and its forked end straddles the cam shaft 15.This forked lever 76 is prorided with. a lateral projecting roller 78,that extends into a cam groove 79 formed in one side of a cam disk 80,which is 'set of bending cams,

mounted on and secured to the cam shaft 15. This cam groove 79 impartsrecip rocal stroke movement tothe forked lever 76, which rocks oroscillates the rock arm 75, causing it to impart a reciprocal stroke tothe piston head 73 in the air cylinder 72, through the medium of theconnecting rods 74., and the alternate outward strokes of the pistoncause alternate air suction movement and force in the nozzle through thepiping connecting the air pump with the nozzle and the air holes thatare open to the atmosphere in the face of the nozzle, which when thenozzle is close to the end card oi the discharge end of the hopper,draws it to it by air suction and grips and holds it'and instantlyafterward the nozzle is moved back from the discharge end of the hopperand conveys the end card to the card stripping device, which releases itfrom the suction grip of the nozzle, and they drop onto stop strips 811in a. position to be acted instantly on by a reciprocating plunger 82,,which moves it into the. first as will be fully explained hereinafter. I

In order that the air impulse nozzle may grip and move and deposit eachcard and return for another card, it must have a reciprocalITIGWPl'llPIllJ bcmvecn the discharge end of the hopper and the bendingdevice, and this reciprocal movement is accomplished by the followinginstrumentalities: The air impulse nozzle is rigidly secured to one endof a. reciprocating bar 83, that is slidably mountedin a slot that isformed in. a lug 84, that forms a. guideway for it, and that is formedin a cross tie, 85, cf the machine; the. opposite end of this leser ispivotally secured to orie end of a link 86, the opposite end of which issecured to one end of a rock arm 87, which is secured on a shaft 88, bya set screw 89, that extends across and is secured in the ends of a pairof upwardly and outwardly projecting brackets 90, that are secured tothe top side edges of the hopper frames 4 and 4:? by cap screws 91. Theopposite ends of the cross tie are secured to these brackets. This crosstie 85 is provided with a lateral projection 92, that extends from ittoward the discharge end of the hopper, that terminates in a forked endportion. The outer end of the forked portion is provided with upwardlyprojecting lugs 93, against which flat straight strips 94 are secured.These strips 1 term the card strippers, as they strip each card. fromthe suction grip of the air suction nozzles on the rearward cardcarrying stroke of the nozzle, as the sides of each card strike againstthis stripper and stop it, while the nozzle passes by the forked ends ofthe pror jet-ting lugs, and these stripperson the back ward stroke ashort distance, and the strippers release each card from the nozzle atpoint that allows it to drop from them onto the stopistrips 81, belowthem; Qne end of i theshaft 88 carries a lever 88-, the free end ofwhich is pivotally connected to a yoke end 9 1 ,',which is adjusthblysecured to one end of a rod 95,.the ,oppositc end'of which is adjustablysecured to, a. yoke'end 96, that is pivotally connected to one end of alever 97. lEhe opposite end of this lever 9.7 is keyed tp a stud pin.98, which is pivotally mounted inandextends through an aperture formedthrough the adjacent side plate.

This pivotal stud pin extendsirom the out side of the side'plate throughand beyond gt far enough to receive one end of a lever 921- which ismounted on and keyed to it, and

the opposite end of this lever 99 extends to the outer side of a camdisk 101, and is provided at its end with a laterally projecting roller102, Which-projects into cam groove 103 formed therein. This cam groove103 and the coiiperating lever members and connections, with the nozzle,are so relativelyi arranged that a reciprocal stroke morcmen' isimparted. to the nozzle that operativel moves the cards from thedischarge end of the hopper to the strippers, and far enough beyond themto allow each card to drop down past the nozzle before it makes itsreturn stroke. Below the strippers, curved chute plates 10% are securedto brackets 105, which are secured to a cross tie 106, that is extendedbetween the sides 4 and t. curved chute plates act to guide each cardThese a card strikes the stop stripsfil, it is en gaged by a plungerplate 82, that is securedto the end of a reciprocating bar 108 and ismoved against vertical bending rolls 109 and109, that are. arranged tobend the end flaps of the cards, as w ll be presently explained. Thisreciprocatin .bar is slidably mounted in a lug 110, that 'epends fromthe center of the cross tie 106, and also in a slidesha ft way 112, thatis formed in the center of the cross tie frame 5 that is secured to theframe 4 and -1 of the machine, and its reciprocal movement is impartedto it by lever and link connections that extend from it to and areconnected to a cam groove in a cam disk on the cam shaft 15, which willbe fully described hereinafter.

The stop strips 81 consist of a pair of flat thin strips of metal thatare secured at one end to a pair of right angular shaped brackets 113;the opposite portions of which are provided with recessed ends 114,which fit slidably and adjustably over a horizontal bar 115, which isadjustably supported upon a vertical post 116 by' a bolt and a butterfly thumb screw, as shown. This vertical post 116 is secured to a headrail 117 by cap screws 118. The horizontal bar is provided with slots119, and the brackets areadjustably secured to this bar by butterflythumb nut screws 120, which extend through the slots and are arranged toclamp the brackets to the horizontal bar in adjusted position, toward oraway from the vertical post, which is positioned in the center of thebending rolls to permit these stops to receive the smallest, as well asthe largest size cards as'they drop from the strippers.

This vertical post 116 is provided with a slot and the'horizontal bar,together with its brackets and the stop strips, can be raised andsecured tothe stop postin ad usted positions. The horizontal bar and thevertical post prevent the cards from falling out under the plunger andback of the side bending rolls.

The plunger plate reciproc'ated to move the cards against the side be grolls by the follruving "nism: To the under side of the bar we, a ip i2is secared, to which one end of a link. 1% is pivotally connected, theopposite end which is pivotally connected to one end of a lever 1:25that is pivotally mounted on. the A lever extends from the hub of thelever 125 and substantially at right angles thereto, the free end ctwhich is piv otally connected to one end of a forked lever 12'2", theforked end of which straddles arranged to impart an intermittent stepand oscillating movement to the forked lever and the link and leverconnections between it and the box, to reciprocate the card plungerplate to operatively move each card against the end and side bendingrollers and into the box corner, as will be fully described hereinafter;The bending rolls 109 and 109 consist of two vertically disposed rollsthat are of triangular shape in cross section throughout their length,except at (their lower ends, Where they are provided with an off-setportion 130. This oif-set portion is provided with a depending hubportion 131. which fits into and is pinned or otherwise secured to asocket shaft 132. This socket shaft extends rotatably through a bearingblock 133, which is secured to the top of the head rail frame 117 anddown into a slot 134, that extends longitudinally i throughout thelength of the head rail frame. The lower end of this socket shaftprojects below the bearing block 133, and on it a bevel gear 135 ismounted, which meshes with a bevel gear 136, that is provided with asquare axial aperture and is loosely and slidably mounted on a squareshaft 137, the opposite terminal ends of which are turned round and arerotatably mounted inbushed bearings formed through the side frames 4 and4. One end of this square shai 't projects beyond the frame 4*, and alever 138 is secured thereon, which is connected. by an arm 38* with onemember 38 of a rocking lever, the other member 38 of which is operatedby a driving cam that is mounted on the cam shaft, which connection willbe fully described hereinafter.

There are two of these vertical end flap 109, is in all respects likethe other side:

bending roll 1-09 and is provided with a similar socket shaft eonnection132 and with a s'milar hearing block 133, and the lower and of thesocket shafbis provided with a sir "lar bevel gear 135, which mesheswith similar bevel. gear 136, that is also slidably lllfll'lilled on thesquare shaft 137, the same as the other ge-ir 136. The object ofslidably mounting the side bending rolls and their supporting socketshafts and driving gears, is to enable the bending rollsto be movedtogether in unison and" toward and away from the center of the machine,which defined by the vertical post 116 to receive and bend the end flapsof cards from the smallest to the largest sizesthe machine is made for.This adjustable feed movement in gs of the socket shafts.

shown in Figs. 32 and 33.

The plunger, whichis of the width of the body of the size of cards beingrun through the machine, and which requires changing to fit each sizecards when the size of cards is changed, moves on its card feedingstroke with an intermittent step by step movement, which is as follows:When a card drops from the strippers onto the stop strips this plungermoves against its central body portion inside of its side and end flapportions and moves it up against the sides of the bending rolls andstops there, while thee-1r suction grips its draws them against the fiatand carry the end the cards along their scored lines, as abovementioned. The rolls. then turn back and then the plunger starts andmoves the card with its bent ends through and past therolls and againstthe horizontally positioned side flaps bendingrolls, and then theplunger will now describe, but. will state; here that after the sideflapsare-w bent over, this plunger again proceeds forward and pushes thenow completely formed the ends of the plunger loose end box into theswinging box feeding frame, which will be presently described. afterwhich the plunger returns to the starting point of its reciprocalstroke.

Each of the side bending rolls 152 and 153 consists of end portions inalinement with each other, having anarrow collar portion at one end andalong roller portion adjacent to its opposite end portion, and with along triangular arranged flap bending portion that is arranged eccentricto the axis of the round end portion, between the-two collar portions,the center or thinnest edge of which is along the axial center of thecollars andopposite end portions of the rolls.

The triangular side flap bending portion ofthe rolls is provided with anair chamber 154, which is preferably made by drilling a hole down intoitfrom preferably its narrowest collar end. The face of the triangularflap bending portion of the roll is provided with a row of air suctionapertures 155,

that extend through it into its air chamber,

all of said apertures, as well as all of the apertures in theendbend'rolls, being employed in forming boxes of the greatestdimensions of which the machine is capable, but when blanks for boxes ofsmalleh'sizes are used, the apertures both in the end and side bendrolls, outside the ends and sides of the blanks are closed by pastingpaper over them, or by covering them with a suitable adhesive material.Each of these bending rolls is provided with an air passage nipple, andapertures that enter the air chamber within them, and suitable piping isconnected to and extends from each roll and is connected into one pipewhich is connected to an air pump cylinder 156, which is provided with asuitable piston and connecting rod 157, which is connected to one end ofa rock arm 158,

' the other end of which is pivotallymounted on the shaft 7 5 This rockarm is connected intermediate 'of its ends, to one end of a forked lever159, the forked end of which straddles the cam shaft 15.- This forkedlever is provided with a laterally projecting roller 160, which projectsinto a cam groove that ,is'formed in the inside face of the cam disk 80,that is mounted on the cam shaft 15.

This air pump during the outward strokes of its piston, creates an airsuction force in each o the side bending rolls that draws and grips hecards tightly against their card engagi .ig surface of each roll whiletherrolls are bending the sideflapsof the cards around the side edges ofthe plunger, which, when this suction action occurs, has moved a cardpast and from the end bending rolls against these side bending rolls.

The side bending rolls are pivotally mounted at one end in head blocks161, and at their opposite ends in bearing brackets,

which are bolted to bracketarms 162, which are bolted at their oppositeends to the head blocks 161. These'liea-d blocks are provided withshouldered slideway portions which fit slidably in a vertically disposedslideway rod is rotatably mounted in a suitable cap 165, through whichit extends, and its terminal end is arranged to receive a suitableWrench by which it may be turned. In order to prevent the accidentalturning of this threaded rod under the weight of the bracket arms, Ithread a set screw 166 through the cap165 against it. The side bendingrolls 152 and 153 are rotatably mounted to stand facing each other. Artthe outer free ends of the arms they are rotatably mounted in bearingbrackets 167, which are secured to the ends of the bracket arms. Theends of the bending rolls which are journaled in bearing aperturesformed in the head blocks, extend beyond the head blocks, and a pinionspur gear 168 is mounted onand secured to each end. These spur gears 168mesh with spur gears 169, which are mounted on and are secured. t6 thehubs of bevel gears 17 0, that are rotatably mounted on stud bolts, thatare threaded into the head blocks 161. The bevel gears 170 mesh withbevel gears 171 that are slidably mounted on a square shaft 172. The

upper end of this square shaft is rotatably journaled in an extension173 of the cap 165. At the lower end ofthe square shaft 172, there is abracket bearing 174, that is secured to the frame 4 of the machine bycap screws.

On the lower end of the shaft 1.72, is a bevel gear 175, the hub ofwhich fits rotatably in the bearing 174 and extends beyond it far enoughto have formed in it a neck portion in which a yoke or crescent shapedplate fits loosely, which is secured to the adjacent end of the bearingby screws 17 6, and is adapted to secure the gear in the bearing, Thebevel gears 171 on the square shaft are held in mesh with the bevelgears-170, as the bevel gears and spur gears are moved toward or awayfrom each other, by the turning of the threaded shaft 164 to adjust theside bending rolls to fit the different sized cards used in the cardbending and feeding machines, by crescent plates 177, that are securedat one end to the head blocks 161, and are provided with a recessed endthat fits loosely over and in a neck portion that is formed in the hubsof the gears 171. The lower gear 175 meshes with a bevel gear 178 thatis supported on a stud screw that is secured to the frame 4, and on thehub of this gear 178, one end of a lever 179 is secured, the oppositeend of which is pivotally secured to one end of a connecting rod 180,the opposite end of which is pivotally con nected to one end of a rockarm 181, at the pivotal center of which. a hub is formed, which issecured to the frame 4 by a stud screw, and from this hub an arm 1.82extends, the end of which is pivotally secured to one end of a forkedlever 183, the forked end of which is arranged to straddle the cam shaft15.

is rigidly secured a lever 219, the outer, end of which is pivotallysecured to one end of a lever 220, which is pivoted at its opposite endto one. end of an L-shaped rock arm 221,

the opposite end of which is pivotally mount- 10!) ed on one end of apin 222, extending through the frame 2", and upon the other end of whichis mounted the hub 38 of the levers 38 and 38. The heel of this rock armis provided with a roller 223, which is arranged 1105 r to pro]ect intoa cam groove formed in the outer face of the cam 12!), which lsmountedon a driving shaft 15. The cam imparts sutli cient movement to the rockarm22l and the lever 219, to cause the gear 217 to turn e 10 quarter ofa revolution, which rotary movement is imparted to the gear 215, anditis turned a quarter of a revolution and it turns the square bar 209aquarter of a revolution.

and -as it does so, it turns an adjustable bracket 224 which isadjustably mounted. on the opposite end ofthe bar 209. This alljustablebracket 224 is secured in adj ust'ed positions by a set screw 225, andit supports at its free end the air impulse device 226,

that grips the blanks and conveys them to the platen 7 of the boxcovering machine, and releases them at a point where the boxes willregister ou-thein. This air impulse box will .be described hereinafter.

The rear end of the square bar extends a shortdistance beyond the bevelgear 215,.and to its end a block 227 is rotatably secured. This block227 is rotatably mounted on 'a reduced round shouldered portion 228 thatis The bevel gear" is provided with a 3.5

which is mounted in the frame 2', whileits shorter member 233ispivotally secured to one end of a yoke lever an, the opposite end ofwhich is provided with a forked end that extends to and straddles thedriving shaft 15, which acts as a support for the forked end of thislever, and permits it to slide reciprocally thereon. This forked leveris provided with a. roller 235 which is secured to it intermediate ofits ends. This roller is arranged to project into a cam groove formed inthe inner face of the cam disk 38, which is mounted on and is secured tothe ram shaft 15. and is arranged to impart a reciprocal throw stroke tothis forked lever and to the crank lever 231 connected to it and to thelink 230. to impart an intermittent reciprocal. stroke movement to thesquare bar 209, whi e the block 227 permits the bar to be turned througha quarter of a revolution on the in; operative stroke of its reciprocalmovement, as will be fully described hereinafter.

It is essential that the bracketfzlzl at the forward end of'thebar 209,have a quarter turn movement on its backward or inoperative stroke ofits reciprocz l movement, in

order that the air impulse box at its end may pass by the form. block7.? of the box covering machine, because the "form block movesimmediately down against the platen the instant-after a finished blankhas been deposited at the box registering point of the platen 7, andthis form block is consequently in the path otthe retu'rn movement ofthe outer end of-the air impulse box.

positioned far enough to one side of the form block 7' to entirely clcar it on its reciprocal strokes, but it is necessary that the air unpulse device at its free end be arranged so that on its operative blankmoving stroke it will move centrally underneath the form block 7 inorder that it may deposit the finishing blanks centrally underneath it.inasmuch as the loose end box that the linishing blank is to cover. isled directly on top of the finishing blank instantlv after C on '{quentln in order that the air impulse box may avoid contact with the formblock 7' on its back. stroke, the. animpulse device must he moved to oneside of the form block at the time it starts to move on its backwardstroke to grip another blank, and this form block clearing movement ofthe air impulse device is accomplished by causing the bracket to turnfrom the downward vertical box is in air gripping relation. to theblanks,

to a horizontal position, which change of position it accomplishes bybeing moved through a quarter circle turning movement 0 by the bar 209,which quarter turning movement turns the air impulse device also fromthe horizontal position in which it receivrs and grips the finishingblank, and moves" it over to and deposits it on the platen and continuesto the end of its operative stroke, at which point it is swung up andchanged from its operative horizontal position into a vertical positionbefore it starts back on its backward stroke, which moves it out of theg0 path of the form block and allows it to pass the form block on itsreturn backward and inoperative stroke. \Vhen, however,fi' t has passedthe form block 7", and before it reaches the end of its backward stroke,it is again turned down into its horizontal position and completes theremainder stroke in that position and moves under at the end of itsbackward stroke another finish'nlgv blank which the air impulse drawsdownagainst it with 2. gripping force that holds it firmly to it, afterwhich it. again starts on its operative blank feeding stroke and movesit over onto the platen T, and thus repeats the ryclc of itsreciprocating 95 movement; and these two quarter turning;- movements ofthe bar, 20$), its bracket 271 i, and the air impulse blank grippingdevig are accomplished by the gears 215 and 217.

This channclbar is closed by ametal strip 236, which is provided with a row of air inlet and outletapertures 23?, which extend the full length of the strip. This airimpulse.

- box'is made long: enough to grip the largest size blanks that are tobe used, and when blanks are used that are of'smallersize than thelargest size blanks used; the air holes in the strip outside of thesesmaller ornarrower H blanks can be closed by pasting pieces of paperover-them. The air box is preferably made to feed blanks for boxes ofdifferent sizes ranging from about 13%} by 209,; inches squarc,down toboxes of about by inches square.

The table 6 upon which the blanks are placed and registered to begripppd by the air impulse box, is adjustably and slidably mounted on asupporting frame 238, by

means of a b 'acket 239, that allows it to be moved-and adjustably setby any suitable means toward or away from the platen 7, of the boxcovering machine, to accommodate it to receive small or large sizefinishing blanks in a registering position that will permit them to begripped by the air impulse box, and the bracket 224 may be adjusted toaccommodate the air impulse lupx to small or large finishing blanks.

As illustrated, the top of the frame 238 is provided with a boltreceiving slot 240, in which the bra ket 23!) of the table 6 is arrangedto lde. and bolts 241, having properly shaped heads. fit into the slotsand clamp the bracket 21-39 of the table to the top of the frame inadjusted positions. The air impulse box 226 projects from the horizontalmember of the bracket 224, and when in an operative blank movingposition stands in a horizontal plane. The horizontal member bracket 224is provided with an entrance aperture. in fwhich is screwed a nipple.242. to which one end of a piece of hose 243 is secured. This hoseextends to and is secured to one end of a pipe 244, the opposite end ofwhich is-secured to the air actuating end of an air pump 245, which ispreferably mounted on the base plate of the box covering machine in aposition [to be actuated from the driving shaft ,of the machine. Thisair pump comprises a cylinder, provided with a suitably packed pistonhead. from which a piston rod 246 extends, and at its outer end it ispivotally connected to one end of a rock arm 247, the opposite end ofwhich is pivotally mounted upon the shaft This rock arm 247 is alsopivotally eonnectral to one end of a forked lever 248. the opposite endof which straddles the driving shaft 15 slidably. This forked lever isprovided intermediate of its ends with a laterally projecting rollerwhich projects into a cam slot that is formed in the inner face of thecam disk 151, which is mounted on and isseeured to the driving shaft 15.

This cam 15], the forked lever 24S and the roc arm 24 7, act undertherotative action discharge end of thehopper, where they are heldby thecorner retaining strips 55 until they are moved slightly back'by theclips, when thesuetion nozzle (55 grips the end one and removes it fromthe hopper. Power is thena'pplied to the friction clutch pulley clipsmove into engagement with all of the,

pack of cards except the end card, and. move the whole. pack back justenough to take the weight off of the end card, and instantly afterwardthe air suction nozzle moves against the end card and grips it by air.

suction force and holds it to the nozzle and conveys it against thestrippers which remove it from thebnozzle, and it drops onto the stopstrips in front of the plunger, which moves it against the end flapbending rolls, at which point the plunger stops until the end flapsfarebent around Lhe ends of the plunger. These rolls grip it by an airsuction force and hold it While the flat sides of the triangular segmentof these rolls as it turns, carries the end flaps of the cards aroundthe corners of the plunger, as is shown in Fig. Some card boards requirethat the flaps of the cards be bent around to about an angle of thirtydegrees, while othereard boards of stiffer quality or of differentthicknesses do not require that the flaps be bent around that far. Theair suction holds the end flaps tightly against the flap engagingsurface of the triangular shaped flap bending rolls, and they are turnedforward to carry the end flaps around the side edges of the plunger andthen turn back again into their inoperative fiat flap receivingposition. The bent end flaps naturally spring backward a little, butremain at about a bent up angle of about eight to twelve degrees from?the right angles, with the bottom or body portion of the card. The firststep forward movement of the plunger and the end flap bending andreturning movements of the end flap bending rolls remain but a fewseconds of time. The plunger then moves forward again and pushes thecard through between the end bending rolls and against the side bendingroll-s, where it again stops, and these side bending rolls grip the sideflaps by suction and bend them around the side edges of the plunger inthe same manner. The box is then formed, and is known as a looserendbox, as while its sides and end flaps are bent up, they are loose andfree from each other. The plunger again moves forward and carries thebox between and past the side rolls and pushes it intothe box carryingframe and between the angular and beveled walls of its clips, and withits bot tom or body portion extending a short disthe taper of thecorners to hold the box fromfalling through the' clips and box carrierframe. Having pushed the box into the box carrier, the plunger startsbaclg on the rearward stroke of its reciprocal movement, and the boxcarr er s swungdownand moved forward with its supporting carriage in theslidevvays of their supporting frames, to-:
